Patti Wilson the career coaching expert says in her Blog:

Its not really a people shortage that is predicted but, rather, a talent shortage. Big difference. Why you ask? Are you asking?
Because, talent is indefinable, subjective. Its really dependent on the whim of a company to decide exactly what kind of "talent" they want to hire and where they must be sourced from. People, on the other hand, may not exactly fit the bill, exactly. A skill may be missing here, an attribute there...it all adds up to available people, ready to work hard, long and diligently...but they just aren't quite the required "talent". Maybe they are too old, too expensive, not from the right competitor...is this what it means for a person to be productized?
